.1 Claim. (01. 29-84) v The present invention relates to the handles of household utensils and tools, and has for its object to provide an improved construction and method of attachingthe metallic ferrules that are customarily employed for the purpose of protecting the ends of handles against wear. Heretofore difficulties have been encountered in holding metallic ferrules in position on handies so that they will not become loose, and .when 0 a ferruleisonceloosened, the handle soon deteriorates 'due to the entrance of moisture into-v the exposed end of the handle. According to the present invention, there is provided an improved ferrule construction and method of attaching the same, whereby a ferrule is so mounted that it is practically impossible for it to become loose from the handle by reason of, its firm attachment to the shank carrying the handle. The above and other advantageous features of the invention will Y hereinafter more fully appear from. the following.

description taken in connection with the accompanying drawing, in which:- Fig. 1 is a plan view of a utensil handle provided with a ferrulemounted in accordance with the invention.

Fig. 2 illustrates the manner of preparingthe' shank of the utensil for the reception of the ferrule.

Fig. 3 shows the manner of applying the handle and ferruleto the utensil shank.

Fig. 4 is a fragmentary sectional view, on an enlarged scale, showing how the ferrule is held.

Like referencecharacters refer to like parts in the different figures. Referring to the drawing, a utensil or tool which may be of any'desired form, as indicated in dotted lines in Fig. 1, provides a metallic shank Ihaving a groove 2 formed therein'near one end. Preferably the groove 2' is made by a rollingor In' Fig. 2a metallic ferrule 6 of cup -shaped form provides a central opening 'I slightly smaller in diameter than the outside diameter of the The ferrule 8 is positioned on a shoulder 8 at one end of the handle 4, the-ferrule B closely fitting the shoulder so that the surface of thehandlel beyond the shoulder a is substan-- tially continuous with the outside surface of the ferrule. The handle 4.. also provides a central opening 9 which is in alinement with the opening I In'the femilewhen the latter is positioned in effect, is peened over into contact withthe on the shoulder 8, the handle opening alsobeing slightly smaller in diameter than the shank 2.

In Fig. 3 the handle 4 carrying the ferrule 6 is shown as having been forced part way on the shank I by pressure exerted in the direction of the arrow, with the shank I itself being heldin the grip of a die I0 closely encircling the shank at the'rim' 3 of the groove 2. Movement of the ferrule 6 on the unreduced shank causes a cer-v v tain amount of expansion around the periphery 10 of the ferrule opening 'I, whi1e'at the same time v the corrugations 5 bite into the wall of the handle Almost-simultaneously with this action, the end of the die engaging the'rim 3 tends to force the 20 rim 3 in close engagement with the ferrule 6 then positioned in the groove 2. The net result is that the ferrule 6 is "clamped tightly between the forward end of the handle 4, then positioned on the shank I, and the deformed rim 3 which,

ferrule. The above described results are shown on a somewhat exaggerated scale in Fig. 4, from which it is evident that the ferrule I5 is held very tightly in position, so that it cannot move on 30 theshank I away from the handle 4 when once the latter has-been forced on the shank I, with the corrugations 5 firmly holding the handle itself in position. The completed utensil then appears as shown in Fig. 1, from which it isevident that 35 the, ferrule 6 appears as an integral part of the handle 4.

From the foregoing, it is apparent that by the present invention there is provided an improved ferrule construction and method of attaching the thereof and forcing a metallic ferrule, having an opening initially smaller than the shank adjacent to the groove, on said shank by the pressure of a handle carrying theferrule until said ferrule is.
